Hi, before anyone jumps in, I have read about 20 different posts in relation to this and none of them are exactly the same as mine.

Started the car today, from first crank it had a persistant tick/click sound like tick tick tick tick and even with throttle it was there and it increase in volume & speed as the throttle increased (using the throttle cable in the engine bay)

(R33 S1 auto, stock turbo, stock inj, stock engine)

I waited a good 5mins before driving the car, opened the hood and my ear was directed towards the top right hand side of the engine bay between the turbo and the wall/flywheel. couldnt exactly pin point but it was louder right there in that corner.

At first I thought it would go away but I had some business to take care of, SO i drove the car 45mins and the click/ticking continued, was faint when driving unless I went pass a car or in a tunnel, but it was still making the noise whilst I was driving the whole time, as well as on Idle parked.

At first I thought it was the lifters but lifters usually sound deeper, then after reading i am thinking it may be a big leak in the exhaust/turbo gaskets causing the noise, as it increased with throttle as if it was controlled by the air passing thru the exhaust.

can anyone shed some light at tell me if its likely to be a leak as it made the noise in Idle and driving, no matter what rpm or speed I did. and its coming from the right side of the engine near the turbo/exhaust!

any advice would be appreciated, its possible gasket or bolts have snapped and caused a leak??????

please help, as I just got myself Z32+nistune today ready to be tuned, but cant do a tune till I sort this out! hoping its just a leak and not lifters! ( it made this noise before I changed ECUs)

thanks heaps

You couldn't have read too many threads...

Exhaust manifold gasket has blown. You'll need to replace it.

Also replace ALL manifold studs at the same time, you will likely have a few broken ones.

Thanks

Ordered Exhaust manifold gasket and the stud kit with all studs/washers etc, will update when they arrive and are put on, that could also explain the low power,

OH then I am getting my new nistune TUNED soon also :D happy happy!

Get the number of a stud remover ready, there is a high chance some will break. My old car, 120xxxkm, all came out smoothly. Amazingly.

How much did the parts cost you?

Mine had a similar problem, it turned out to be a loose wastegate, over time the actuator had lost its preload. Easy way to tell is to start the engine (preferably cold) and pull on the wastegate arm and see if it stop. Worked for me! :)

      R32 GTS (RB20DE) Injectors Replacement

      By joshuaho96 · Posted

      Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs.

      This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
